Transcriptional regulation of the Japanese flounder Cu,Zn-SOD (Jfsod1) gene in RAW264.7 cells during oxidative stress caused by causative bacteria of edwardsiellosis
In this study, NUF251 stimulated intracellular superoxide radical production in mouse macrophage RAW264.7 cells, which was reduced by N-acetylcysteine. This result suggests that NUF251 infection causes oxidative stress. To evaluate the regulatory mechanism of Jfsod1 at transcriptional levels under oxidative stress induced by NUF251 infection, we cloned and determined the nucleotide sequence (1124 bp) of the 5'-flanking region of the Jfsod1 gene. The sequence analysis demonstrated that the binding sites for the transcription factors C/EBPα and NF-IL6 involved in the transcriptional regulation of the mammalian sod1 gene exi...

Current Status and Problems of Newborn Infection Management at a Regional Hospital in Japan
CONCLUSIONS: There were no asymptomatic cases of CRP >2 mg/dL, and no cases of severe sepsis in normal neonatal deliveries. CRP levels were elevated in the AFT group, where culture was positive, but few antibiotics were administered. In the C/S group, antibiotics were administered if respiratory symptoms occurred unless the CRP level was high. Further, all patients in PROM group who received antibiotics had any symptoms, suggesting that routine blood tests may not be necessary.PMID:37661631

Solubilization of Poorly Water-soluble Drugs with Amphiphilic Phospholipid Polymers
Yakugaku Zasshi. 2023;143(9):745-756. doi: 10.1248/yakushi.23-00023.ABSTRACTMost drug candidates developed in recent years are poorly water-soluble, which is a key challenge in pharmaceutical science. Various solubilization methods have been investigated thus far, most of which require solubilizers that provide a local hydrophobic environment wherein a drug can dissolve or induce interactions with drug molecules. We have focused on amphiphilic 2-methacryloyloxyethyl phosphoryl choline (MPC) polymers. In addition to the ease of molecular design of amphiphilic MPC polymers owing to their chemical structures, they have been r...

Yakugaku Zasshi. 2023;143(9):729-744. doi: 10.1248/yakushi.23-00017.ABSTRACTCellular aging is one of the most extraordinary phenomena that mammalian cells undergo in vivo and in vitro. We have been observing their behavior for approximately 4 decades and here would like to summarize some of our salient findings. Normal cells such as human diploid cells exhibit finite growth potential in vitro as well as a set of senescent cell phenotypes. Those changes appear probabilistic and irreversible. In the search of the factor(s) to evoke the features we have observed that cellular glycosaminoglycan molecules plays significant role...

Elucidation and Prediction of Absorption Behavior After Oral Administration of Poorly Water-Soluble Drugs as Different Lipid-Based Formulations
Yakugaku Zasshi. 2023;143(9):721-727. doi: 10.1248/yakushi.23-00092.ABSTRACTLipid-based formulations (LBFs) are isotropic mixtures typically comprising lipids, surfactants, and/or co-solvents, in which drugs are pre-solubilized. After oral administration, LBFs are piggybacked into endogenous lipid digestion pathways. This triggers drug super-saturation and improves absorption. However, super-saturation poses a risk of drug precipitation, which generally leads to poor drug absorption. Furthermore, a series of aqueous colloidal species including digestion products (typically fatty acids and monoglycerides) and endogenous mol...

Development of Molecular Transformation Reactions Using Visible Light and Main Group Elements
Yakugaku Zasshi. 2023;143(9):693-699. doi: 10.1248/yakushi.23-00091.ABSTRACTOwing to their ability to induce excitation of specific molecular orbitals or initiate chemical reactions, photochemical reactions have the potential to be more effective at selectively activating target molecules than thermal reactions. The thermal reactions transfer thermal energy to activate molecules, which often leads to the activation of multiple molecular species, including undesired ones, resulting in non-selectivity. This nonselectivity may result in undesirable side reactions or decrease reaction efficiency. Additionally, photochemical re...
